To alvlwemz'tmaycon'cem: y

v it knownthat 1, ,FRANK W. Bourne, a citizen ofthe Dominion of Canada, and a resident of the city of Bellingham in then county of Whatcom and'St-ate of l/dashington, have invented certain new and useful.' Improvements in Conveyers, of which the following is aspeciiicat-ion, the same being a division of? myy application Serial No. 641,940, filed August 2, 1911.

' My'- invention has for'its primary object to pro-vdemecha'nisin of the abovey type embracing one 'or more angularly adjustable work holders,- togethen with means for edecting" theadjustment diereo'during their conveyan.

@ther objects will be set forth as my description progresses and those features ot construction, arrangements and combinations off partey -on which Il desire protection, succinctly defined in/my annexed claims.

- Referringto the accompanyingl drawings wherein' 'like numerals of reference indicate like'parts throughout: Figure l is a side elevation of a receptacle coating machine em? bod'ying the features of my invention in such form as now preferred by me, parte being"Y brokenlaw'ay. .Figa 2' isa 'planet the same with portions of some of the parts broken away. Fig. 3 is a vertical transverse section on line 3 3 of Fig. 1. Fig. t is a side eleva! g tion' illustrating fragmentarily fthe carrier,

the guides or track and the provision for removing the' coated receptacles from the carrier, and Fig. 5 is a horizontal section on line o o-of ldig'. 4.

For the purpose of illustration, ll have shown my invention employed in a receptacle coating machine, forming the subject matter of my said application Serial No. 641,940,1iled Aug. 2, 1911, in which the receptacles are advanced sidewise'for coating, then upendcd for dripping and'- nally inverted for delivery. s p

'Referring to the drawing by numerals ofv reference, 2 indicates work holders, ofvpreferred form, for supporting tapered recep tacles or bottles, as 1. Work holders 2 are combined with a carrier in the form of a swivel link belt 3 which extends about guiding sprocket wheels 4, 4 and 5 with a portion of its upper run sagging in an elevated tank 6 between driving sprocket wheels 7, 7 fixed to shafts 7', 7 which are journaled on the tank-and connected by link belt geardrive pulley 9 to which power is applied tto operate belt 3 in the direction indicated :by the arrow in lliig. 1'..

The holders 2, which are designed to receive receptacles 1 sidewise, each comprise gconcaved side seats 20, 21, secured to re- Aspective end portions of a base 22 and provided with inwardly projecting flanges 20', `i21 which serve as end guards to hold the 'gre'ceptacle seated in the holder from endwise displacement. In this connection it will be iobserved that `tlie'base parts of the holders extend crosswise of and are secured to respecti've link sections of belt 3 inalternate Earrangement-4 with swivel" coupling sections i3 which permit of' angularadjustmcnt of lithe holders to upend the receptacles. Tank 6 is equipped'with a receptacle guidiing device comprising circular members 11,

g' 11, secured to a shaft 12 which is positioned @between-the wheels 7 vand journaled on the :tank inconce-ntric relation withdepending v,semicircular guides or tracks 13disp`osed at opposite sides of belt 3 for guiding engagement with opposite angular lugs 23 of the holders 2 and extending into angular approach and delivery guide sections 13, 13 which are secured'to respective` brackets 10 of tank 6.

rEhe receptacles'l lare placed inthe holders advancing along the approach guide sections 13' and thence carried along the guide secvtions 13 in engagement with the rotatable l members 11, 11 which retain the receptacles in the holders during their immersion in a body of parafn, as'C," .contained in tank 6 and maintained', as will be ylater understood, in a fiuid state.

Extending from the guide sect-ions 13 'are quarter turn spiral guide sections 3, la

adapted to upend the holders advancing from. the-tank and connected, respectively, withhorizontal guide sections 3b, 4", which extend over an inclined trough part 6 of tank 6 and serve to guide the holders in up.- ended position with the receptacles mouth down for dripping.

Extending'from the guidescctions 3b, 4" and secured to other fixed brackets 10 are haltl t-urn, spiral guide sections 3C. 4C adapted to invert the holders advancing from trough 6 and connected, respectively with horizontal guide sections 3d, 4". 'llhese guide sections 3d, 4d-whch serve to guide the holders with the receptacles bottom down for delivery, are provided Withquarter turn spiral terminat-ions 3e, 4? for guiding the empty holders to horizontal position.

designates a curved delector secured to a bar extension 15 of trough 6 and positioned between the guide sections 8d, 4d in the path of the holders 2 :tor directing the receptacles therefrom for delivery to a conveyer 16, comprising a link belt extending alongside bar 15 in parallel arrangement with elevated side guides 17, 17 andtaking about sprocket wheels 18, 18". Conveyer 16 is conveniently driven through the medium of a link belt 16 applied'to suitable sprocket wheels secured to shafts 18', 4l which are j ournaled, in fixed connection with the wheels 18,4 respectively, on a bracket 19 supported in common -with the journal bearin 19 of wheel 4, on a standard 19.

Com ined with tank 6 is a chamber 6 provided with a drain cock 24 and cont-aining a pipe coil 25 which is connected through circulating pipes 26, 26 with a Water heater, not shown, carryinI water at suitable temperature to maintain te paramn in tank 6 at a proper temperature for coating.

Positioned beneath the lower run of belt 3 is an auxiliary steam heating appliance in the form of a pipe coil 28 whichv is connected with a generator, not shown, to be served with steam at suitable temperature to maintain a heated zone about the belt of sutlicient intensity to clear the holders 2 of coating material as theyv pass between the wheels 4', 5 in guiding engagement with a late or strip 29 which is supported with coil 28 on cross pieces fixed to the legs of tank 6, as

clearly shown.

rlhe term work holder as herein em-l ployed is intended to cover broadly any de vice or contrivance which can be mounted on the swiveled carrier-sections for operation through adjustment of the latter.

Having thus described my invention, what l claim as new, and desire tol secure by Letters Patent of the United States of America, is

1. In a machine of the character described, an endless flexible carrier supported for inrosa@ movement, said carrier having one section of its length "swiveled at each end, a work holder xed to the swiveled section of said carrier, and means for adjustingv the swiveled section of said carrier during movement of the latter.

2. ln a machine of the character described, an Vendless Hexible carrier composed of link sections Vand swivel coupling sections arranged between said link sections and conneet-ing the same,

on the link sections of said carrier, and

means for adjusting the link sections of said,

carrier by and during vmovement of the latter. A

3. ln a machine of the character described, an endless lexible 'carrier supported for movement and provided with a swiveled section, a work holder on the swiveled section of said carrier, means 'for adjusting the swiveled section of said carrier by and during movement of the latter, said means comprising a track arranged in the path of saids'ection and spaced angular lugs on said work holder engaging under said track.

4. A' conveying mechanism comprising a carrier, a work holder supported on said carrier for angular adjustment, said work holder comprising spaced concaved seats openqat one side for removal of the work therefrom, means for adjusting said work holder during movement of said carrierto bring the work to a vertical position, and means for removing the work from said work holder when the work is in verticalposition.

5. A conveying mechanism comprising a carrier, a work holder supported on said carrier for angular adjustment, said work ,holder comprislng spaced end seats open at one side for removal of the work therefrom, means for adjusting said work holder during movement of said carrier to diderent angular positions, and means :t'or removing the work through the open sides of the seats of said work holder.
